Evaluation of Collectible Material by Sources Selectively Valuable Traits

The research was conducted in 2022–2024 in the Ulyanovsk region in order to evaluate the collection material according to the main economically valuable characteristics in order to identify the best samples. The object of research was 110 collectible samples of seeded peas of various ecological and geographical origin, the standard – zoned variety of the Pendant. As a result of the study, sources of high seed productivity were identified – Buslay (RF) (3.93 t/ha), Poltavets (Ukraine) (3.96 t/ha), Tsarevich (Ukraine) (3.99 t/ha), which is 6.1…10.8 % significantly higher than the standard. The samples G. 0000557 (China), Lu 153-06 lupinoid (Russia), Waldmanns (Ger- many), Ul-319/17 (Russia), characterized by the largest number of productive nodes (5.0…6.2 units, which is 8.7…34.7 % higher than the standard variety, were identified as valuable sources of traits that determine seed productivity. Tsarevich (Ukraine) and B-3729/2 (Russian Federation) turned out to be sources of high seed weight from the plant (1.5 g). A high number of seeds from the plant was found in samples Yamalsky 305 (RF) and Waldmanns (Germany) (25.7 and 23.8, respectively). The best performance indicators for bob were demonstrated by Streletskiy 11 (RF) (6.0 units), KT-6506 (RF) (5.8 units) and SH-95-69-3 (5.6 pcs.), which is 1.6…2.0 pcs. higher than the values of the standard grade. Schors Rappoldshofer (Germany) (350.4 g), 9964 Mexico (309.4 g) and Kumir (RF) (258.7 g), which surpass the standard Kulon variety by 20,8…80 %, were identified as sources of a high mass of 1000 seeds. The sources of stunting and resistance to lodging 9 points are highlighted – Azur (Germany) – stem height 37.4 cm, Ul-355/17 (Russia) – 31.6 cm, Biathlon (France) – 30.7 cm (22.6…29.3 cmbelow the standard). The isolated pea samples will be used as genetic sources in crossbreeding, which will allow the creation of new pea varieties that combine high productivity, quality and resistance to lodging.
